This article introduces the "java jar package to generate exe files" related knowledge, in the actual case of the operation process, many people will encounter such a dilemma, and then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!

Related software: IDEA exe4j

JAVA Technology: maven SpringBoot jna

Application environment: windows7/10

MAVEN information

Net.java.dev.jna jna 5.6.0 org.springframework.boot spring-boot-starter-web org.projectlombok lombok 1.16.18 junit junit 4.12 Test org.junit.jupiter junit-jupiter RELEASE compile org.springframework.boot spring-boot-starter-test test org.junit.vintage junit-vintage-engine

First, MAVEN the SpringBoot project into a jar package.

@ RestControllerpublic class PublicApi {@ RequestMapping ("test") public ApiResponse testApi () {/ / DhScalePluNet is the name of the DLL file. This is the way to get the relative directory. The absolute directory can own Baidu CLibrary instance= Native.loadLibrary ("DhScalePluNet", CLibrary.class); int I = instance.dhSendPluDefault (); if (I! = 0) {ApiResponse result = new ApiResponse (ErrorCode.ERROR). Result.setResult (I); return result;} return new ApiResponse (ErrorCode.NO_ERROR);} @ RequestMapping ("test") public ApiResponse testApi () {String pa = new File (".") .getAbsolutePath (); pa = pa.substring (0, pa.length ()-1); pa = pa + "DhScalePluNet" Pa = pa.replaceAll ("/", "\"); log.info ("full path:" + pa); / / full path this path is the file path where exe is executed. After the application is packaged, dll | ini and other files will be in the same level directory as exe file CLibrary instance= Native.loadLibrary (pa, CLibrary.class); int I = instance.dhSendPluDefault () If (I! = 0) {ApiResponse result = new ApiResponse (ErrorCode.ERROR); result.setResult (I); return result;} return new ApiResponse (ErrorCode.NO_ERROR);}}

Project DLL file placed in the pit, generally can not read DLL, this time you need to put the DLL file into the win32-x86 directory to read. And my DLL is 32-bit DLL. 64 is still unknown.

After passing the local test, you can package it with the IDEA MAVEN plug-in.

The detailed usage tutorial for exe4j:

Then generate EXE file, your DLL file and EXE in the same directory level can be called normally.
